Ok, so I decided to do a little bit of research (not much .... like minimal), and I since I am not that versed in the innerworkings of how GPUs work, I was wondering if someone could help clear this up for me.

So I am comparing the Nvidia GT 710 vs Intel HD 520, and I have come up with some conflicting evidence of which one is "better" for lack of a better term.

Intel HD 520 Better

1. [[Please login to see this link.]]

2. [[Please login to see this link.]]

Nvidia GT 710 Better

1. [[Please login to see this link.]]
2. [[Please login to see this link.]]

Basically, from 1. in the Nvidia section, it seems to run definitely faster than 2. (they have more or less the same processor and RAM, etc.). Can someone explain the discrepancy between performance in-game and benchmarks that clearly state that the Intel HD 520 is better.

TL:DR Why do benchmarks say that the Intel HD 520 is better than the GT 710 in 80-100% of aspects, but in a game, the GT 710 seems to provide better FPS. Is this possible, am I missing something, or what?

Thanks!

Always look for real benchmarks. The above two sites you linked are automated benchmarks based solely on GPU specs and they don't reflect real performance. Never trust these benchmarks!

Now the GT710 doesn't really have many reviews since it's an entry level GPU, so your only option is to see a gameplay of both cards on youtube for the same game and compare yourself, which you already did.

It depends on the type of game engine/3d rendering software that utilizes the architecture properly. One good example of this is testing tessalation rendering on both cards and you'll see differences. Usually proprietary standards does play a role in performance ex. Nvidia's Cuda engine.

@ michael.rol
well for starters which GT 710 are you referring to? the GDDR3 or GDDR5 version?

because it ranges quite a bit in specs:

6.6 GP/s 13.2 GT/s 316 GFLOPS 0.5/1/2 GB GDDR3 14.4 GB/s

or

7.6 GP/s 15.3 GT/s 366 GFLOPS 2 GB GDDR5 40 GB/s

the GDDR5 version is about 30% faster than the GDDR3 version.

Intel HD Graphics 520 best case scenario (1050 MHz and dual-channel DDR4 2133 MHz RAM):

3.15 GP/s 25.2 GT/s 403.2 GFLOPS 1.68/3.75 GB DDR4 34.1 GB/s

they trade blows. technically the GT 710 2 GB GDDR5 is going to be slightly faster (5-10%) than the best case scenario for the HD 520. but the HD 520 will typically be faster than the GT 710 GDDR3. however, this is dependent on RAM speed, whether it is single-channel or dual-channel, as well as core clock. all of which varies depending on the laptop.

so basically to answer your question, it depends. both GPUs vary about as much among themselves as they do between each other.

@ Jake_Ro_X
in some cases sure, but generally speaking it has more to do with driver support. even the same GPU can have a 10% increase in performance by updating drivers. and since NVIDIA has better drivers, expect slightly better performance with identical specs.

FPS isnt the only thing that matters, also the quality and thats were nvidia is known to fall back in the past even in the 90s [[Please login to see this link.]] 2k15 line up [[Please login to see this link.]] 2k13 line up [[Please login to see this link.]] and in 2003 they did already that. So i would recommend just to get the card that is if cheapest for you.
Please keep in mind that especially today most games are poorly optimised if it all so the manufacturer has to optimize theyre drivers for the game. Also amd dropped legacy support so if you want to play older games stay away from amd cards. Futuremark also found that the benchmark scores of nvidia are fake "we have now established that nvidia's detonator fx drivers contain certain detection mechanisms that cause an artificially high score when using 3dmark�03. we have just published a patch 330 for 3dmark03 that defeats the detection mechanisms in the drivers and provides correct results. "
